TOP roe GAS-RANGES.

Specification of Letters Patent. Patented Feb, 8, 1916.

Application filed January 12, 1914. Serial No. 811,574.

To all whom it may concern:

Be it known that I, MARTIN W. LONG- rELLow, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventednew and useful Im-z provements in Tops for Gas-Ranges, of which thefollowing is a specification.

This invention relates to an improved top for gas ranges.

- In gas stoves and ranges as now constructed, the topwhich supports thearticles to be heated above the gas flame, is usually constructed in theform of a grid or grill. This construction is open to objection for thereason that the overflow from the cooking passes through to the panwhich is usually located below the burners. Furthermore the open top ofthis type is open to objection because there is no surface which is warmenough to keep cooked articles from' cooling rapidly.

I One of the objects of the present invention like, which may be readilycleaned and so 25 constructed as to prevent a large portion'of theoverflow from the cooking from running through to the pan which islocated below the burners. v

A further object is to provide a top which will permit the shifting ofthe cooking vessel to a surface which will be more or less warm, due toconductivity.

A further object is to provide a top so constructed that air currentsare prevented from interfering with the direct contact of the flame orheat with a vessel supported by said top, whereby concentration of theheat is eflected.

A further object is to provide a top having openings arranged above theburners,

but otherwise imperforate, and having' means for providing heat channelswhich will permit of the passage of heat from'the,

tect the burners.

The invention will be hereinafter fully set forth and particularlypointed out in the claims. I

In the accompanying drawings :Figure 1 1s a top plan view illustrating asimple type of gas-stove with my invention applied thereto. Fig. 2 is alongitudinal sectional view of the top plate and Fig. 3 is a transversesectional View thereof. View of the top removed. Fig. 5 is a plan viewof a slight modification.

Referring to the drawing, 10 designates a gas stove body supported bylegs or standards 11 and provided with the burners 12, the latter beingconnected with a suitable supply pipe 13, said burners and supply pipebeing supportedby arms or brackets 14. It will be understood that whileI have shown and described this simple form of gas stove forillustrative purposes, my present invention is not limited thereto butis applicable to all forms of gas stoves, nor

ing therefrom. 'lhe body of-the plate is cut away to form radiatingrecesses 19 in the depressed portions 18 andbetween the ridges 17, toconform to the shaft of the burners. If desired a simmer burner may beemployed, 'in which event the plate is provided with an opening 20 abovesaid burner, said opening being surrounded by alternating ridges anddepressions 21, 22 respectively.

From the foregoing it will be seen that my improved top is open only atpoints immediately above or opposite the flame of each burner, and thatbetween the flames there is a ridge and ,a depression both of whichserve to permit the escape of the products of combustion. Thedepressions serve to catch and retain a large percent-- MARTIN W.LONGFELLOW, 0F BALTIMORE, MARYLAND, ASSIGNOR TO THE BALTI- '60 Fig. 4 isaage of the overflow from the cooking, and the arrangement is such thatthe top may be readily and easily cleaned. Said depressions also serveas channels. \Furthermore the top as an entirety is heated to a greateror less extent by the gas flames so that cook, ing vessels may-beshifted from points over I the flames, and yet be kept warm due to thegrates '22 provided with raised ribs 23 ar-' ranged in prolongation ofthe ridges 17.

Having thus explained the nature of my invention and described anoperative manner of constructing and using the same, although withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, what I claim is 1. A top for gas ranges and thelike comprising a plate formed of a single piece of metal havingopenings adapted to register with gas burners, said plate having anundulating top surface between and around all of saidopenings, thedepressed portions of said surface forming draining channels for theareas between said openings, and adapted to cooperate with a vessel uponsaidplate to form flues leading from the burners.

'2. A top for gas ranges and the like com prising a plate provided withopenings adapted to register with gas burners, the top surface of saidplate having undulations radiating from and surrounding the respectiveopenings, the depressed portions of said surfaces forming drainingchannels for the areas between said openings and adapted to cooperatewith a vessel upon said plate to form flues leading from the burners.

3. A top for gas ranges and the like comprising a plate formedof asingle piece of metal provided with spaced apart openings adapted toregister with the'gas burners, and having alternating ridges anddepressions between and around the respective openings, the depressionsforming draining channels for the areas between said openings, andadapted to cooperate with a vessel upon said plate to form flues leadingfrom the burners.

4. A top for gas ranges and the like comprising a plate formed of asingle piece of metal having openings adapted to register with gasburners, said top plate having an undulating surface between and aroundthe respective openings, the depressed portions ofsaid surface formingdraining channels for the areas between said openings, and adapted tocooperate with a vessel upon, said plate to form fiues leading from theburners, the depressed portions being provided with radiating recessesarranged around said opemngs.

5. A top for gas ranges and the like comprising a plate formed of asingle piece of metal provided with spaced apart openings adapted toregister with the gas burners and having alternating ridgesjanddepressions between and around the respective openings, the depresionsforming draining channels for the areas between said openings, andadapted to cooperate with a vessel upon said plate to form flues leadingfrom the burners, in combination with ring grates located in saidopenings and provided with raised ribs in prolongation of said ridges.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
